I have an old french pistol that my grandfather gave me years ago. He took it off a french pilot at the end world war 2. It is very small pistol with a clip that holds about 6 to 8 rounds. The barrell flips up. The letters MF are on the side and bottom of the grip. The writing is in french but it looks like it says manufactured by french arms of saint bienne. Can anyone tell me anything about this gun. I want to know about it so I can pass on to my son. I appreciate your help.
